PURPOSE:To prevent sticking during heat transfer from occurring, and to prevent strike-through of a dye from an ink layer to a heat-resistant slippage layer during storage from occurring. CONSTITUTION:In a heat transfer sheet with an ink layer on one face of a sheet-like base material and a heat-resistant slippage layer on another face, a polyvinyl acetal resin, a polyisocyanate, phosphate-type surface active agent and a 10-22C linear fatty acid are incorporated in the heat-resistant slippage layer. The heat-resistant slippage layer is formed by applying a compsn. for the heat-resistant slippage layer wherein 30-80wt.% polyvinyl acetal resin, 5-50wt.% polyisocyanate, 5-30wt.% phosphate-type surface active agent and 1-20wt.% 10-20C linear fatty acid in the solid content are incorporated, and the incorporated sum of the phosphate-type surface active agent and the 10-22C linear fatty acid is at most 30wt.% on the sheet-like base material and curing it. |
